CLAUDE W. IBISSELL, OF TORONTO, ONTARIO, CANADA, ASSIGNOR TO JAMES HOWARD FRANKLIN, OF WATFORD, ONTARIO, CANADA.

CAP FOB MILK BOTTLES.

Application filed June 28, 1923.

To all whom it may concern:

Be it known that I, CLAUDE W. BIssnLL, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Caps for Milk Bottles, of which the following is a specification.

This invention relates to the cardboard caps commonly used as the closures of milk bottles and adapted to be pressed into the mouth of the bottle and to rest on an annular seat formed within the mouth, and my ob:-. ject is to devise a cap which will form as: effective a closure as the present cap while it is much more easily removed and replaced, and presents also three surfaces for the display of advertising matter.

I attain my object by means of the cone structions hereinafter described and illustrated in. the acompanying drawings in which- Fig. 1 is a plan View, on an enlarged scale, of my improved cap;

Fig. 2 a cross section on Fig. 1;

Fig. 3 a similar View with the upper disk raised; and

Fig. 4 a plan View of the blank from which the cap is formed.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The cap is formed of two cardboard disks 1 and 2. These may be formed of somewhat lighter stock than the single disks commonly employed, so that the combined thickness of the two is about the same or not materially greater than the single ply caps. The disks are circular in form, so that the entire edge of each will engage the inside of the mouth of the bottle when they are pressed into position.

While the disks may be entirely separate, they are preferably integrally united along a small are 3 of the rim of each disk. This connection being very narrow, the periphthe line 22 in cries of the disks substantially contacting,

the double disks shows little, if any, departure from a true circle, so that it will erfectly fit the internal surface of the mouth of the bottle affording a tight seal.

Just in front of the integral connection of the two disks I form a hinge by means of a staple connecting the two disks and preferably formed of non-corrosible wire or Serial No. 6&8338.

wire coated with a non-corrosible metal. To facilitate the swing of the upper disk 1 on this hinge, I form a line of weakness just in front of the hinge. This may be formed in various ways. I show a cut 5 formed-completely through the upper disk,which cut extends only part way towards the rim of the disk at each side, sufficient connection being left for purposes which will hereinafter ap pear.

Adjacent the rim of the disk 1 opposite the hinge, I foim an integral tongue 6. This is preferably formed by a double cut so that the edges of the tongue are quite free of the edges of the hole, thus formed in the disk. The tip 7 of the tongue is also preferablycut away to facilitate the introduction of a pointed tool beneath the tongue to raise the same.

So that the attention of the user will be directed to this tongue and its function the tongue is colored to contrast strongly with the remainder of the disk and an arrow 8 is imprinted on the disk leading to this tongue.

The cap is used as follows: The milk bottles are sealed with a cap in the usual manner and delivered to the user. When it is desired to open the bottle, the tongue 6 may be lifted by the use of a pointed tool or the thumb nail and used to lift the upper disk. The upper disk is then pulled up and the lower disk thus Withdrawn from the mouth of the milk bottle, lifting taking place, of course, at the hinge side. hen the bottle is to be temporarily rescaled, it is merely necessary to push the disk 2 down into position, the disk 1 usually remaining partly or wholly raised.

From this it follows that both sides of the upper disk and the upper side of the lower disk are seen by the user of the bottle, so that all three surfaces may be used for the display of advertising matter. Usually the upper surface of the upper disk will bear the advertising of the milk dealer, while the under surface of the upper disk and the upper surface of the lower disk may be used for the advertisements of those willing to pay for the use of such an advertising medium.

The integral connection 3 between "the disks has value in connection with the manufacture of the disk for the reason that it ensures that the two disks will have a fixed position relative to one another, so that the advertising smatter on wtheunder side of the upper disk and the upper-side of the lower disk Will be properly alined, so that it may be read from one position, Without special care being necessary to properly position the two disks as Will be the case if they were entirely separate and separately printed.

What I claim is 1. A bottle cup formed of tWo separate and similar: circular disks of-the same thickness and; diaineteiylanid together of substantially. thesamefthickness as a common commercial milk bottle cap, stapled :together adjacentthe rim of the cap to form'ia hinge, an integraltongue being formed Within the periphery of the upperdisk diametrically opposite the hinge whereby it may be raised, and a line o'f'weakness for-med in the disk adjacent the hinge and parallel. thereto.
